Configuring for Survivability 319
Configuring IP Line data on survivable Small Systems
When the VGMC is installed in the Main Cabinet or Chassis, only one IP
address is required. When the card is installed in a survivable IP expansion
cabinet or chassis, two IP addresses are required. The first IP address is for
the Main Cabinet or Chassis SSC. The second IP address is for the SSC in
the survivable IP Expansion Cabinet or Chassis that has the VGMC.
Each IP Phone configured on the VGMC must have the IP address of the
survivable IP Expansion Cabinet or Chassis configured as the second IP
address. These IP addresses must be on the same subnet.
Refer to Procedure 50 "Configuring the ELAN network interface IP address
for the Small System active ELNK Ethernet interfac" (page 265) and
Procedure 51 "Configuring the ELAN network interface IP address for the
Small System active ELNK Ethernet interfac" (page 266)
to configure the
Small System’s Main Cabinet or Chassis and any IP Expansion Cabinets
or Chassis.
